Methods and compositions for treating abnormal cell growth

ABSTRACT

The present invention relates to, inter alia, combinations, methods, compositions, and oral dosage forms of a FAK inhibitor and a MEK inhibitor, for treating abnormal cell growth (e.g., cancer).

CLAIM OF PRIORITY

This application is a National Stage Application under 35 U.S.C. § 371 of PCT/US2015/014843 filed Feb. 6, 2015, which claims priority to U.S. Provisional Patent Application No. 61/937,253 filed Feb. 7, 2014. These prior applications are incorporated by reference herein in their entirety.

BACKGROUND OF INVENTION

Convincing evidence suggests that focal adhesion kinase (FAK), a cytoplasmic, non-receptor tyrosine kinase, plays an essential role in cell-matrix signal transduction pathways (Clark and Brugge 1995, Science 268: 233-239) and its aberrant activation is associated with an increase in the metastatic potential of tumors (Owens et al. 1995, Cancer Research 55: 2752-2755). Selective inhibitors of certain non-receptor tyrosine kinases, such as FAK (focal adhesion kinase), Ick, sre, abl or serine/threonine kinases (e.g., cyclin dependent kinases), are useful in the treatment of abnormal cell growth, in particular cancer, in mammals. FAK is also known as the Protein-Tyrosine Kinase 2, PTK2. Compounds, compound combinations, compositions, and methods for inhibiting FAK in a subject are therefore desirable. FAK expression and/or activity has been reported to be upregulated in a range of malignancies, including cancers of the thyroid, prostate, cervix, colon, rectum, oral epithelium, ovary, and breast.

Components of the Ras/Raf/MEK/ERK signal transduction pathway also represent opportunities for the treatment of abnormal cell growth, e.g., cancer. MEK proteins are the primary downstream targets of Raf. The MEK family of genes consists of five genes: MEK1, MEK2, MEK3, MEK4, and MEK5. The MEK proteins belong to a family of dual-specificity kinases that have both serine/threonine and tyrosine kinase activity. MEK inhibitors have shown potential therapeutic benefit, for example, for inhibiting human tumor growth in nude mouse xenografts (Yeh, T. et al, Proceedings of the American Association of Cancer Research 2004, 45, Abs 3889). The MEK/ERK pathway has also been implicated in the self-renewal of cancer stem cells in breast and prostate cancer (Balko et al, Cancer Research 2013; Rybak et al, PLoS One 2013).

This disclosure is not limited in its application to the details of the methods and compositions described herein. Also, the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

Definitions

As used herein, the articles “a” and “an” refer to one or to more than one (e.g., to at least one) of the grammatical object of the article.

“About” and “approximately” shall generally mean an acceptable degree of error for the quantity measured given the nature or precision of the measurements. Exemplary degrees of error are within 20 percent (%), typically, within 10%, and more typically, within 5% of a given value or range of values.

As used herein, an amount of a compound or combination effective to treat a disorder (e.g., a disorder as described herein), “therapeutically effective amount”, “effective amount” or “effective course” refers to an amount of the compound or combination which is effective, upon single or multiple dose administration(s) to a subject, in treating a subject, or in curing, alleviating, relieving or improving a subject with a disorder (e.g., a disorder as described herein) beyond that expected in the absence of such treatment (e.g., placebo treatment).

The term “pharmaceutically acceptable,” as used herein, refers to a compound or carrier (e.g., excipient) that may be administered to a subject, together with a compound described herein (e.g., a FAK inhibitor, a MEK inhibitor), and which does not destroy the pharmacological activity thereof and is nontoxic when administered in doses sufficient to deliver a therapeutic amount of the compound.

The term, “pharmaceutically acceptable salts,” as used herein, refers to derivatives of a compound described herein (e.g., a FAK inhibitor, a MEK inhibitor), wherein the compound is modified by converting an existing acid or base moiety to its salt form. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts of the disclosure include the conventional non-toxic salts of a compound described herein (e.g., a FAK inhibitor, a MEK inhibitor), formed, for example, from non-toxic inorganic or organic acids. The pharmaceutically acceptable salts of the disclosure can be synthesized from a compound described herein (e.g., a FAK inhibitor, a MEK inhibitor), which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 17^(th) ed., Mack Publishing Company. Easton, Pa., 1985, p. 1418 and Journal of Pharmaceutical Science, 66, 2 (1977), each of which is incorporated herein by reference in its entirety.

The phrase, “pharmaceutically acceptable derivative or prodrug.” as used herein refers to any pharmaceutically acceptable salt, ester, salt of an ester, or other derivative of a compound. e.g., a FAK inhibitor, a MEK inhibitor, which, upon administration to a recipient, is capable of providing (directly or indirectly) a therapeutic agent. Particularly favored derivatives and prodrugs are those that increase the bioavailability of a compound described herein (e.g., a FAK inhibitor, a MEK inhibitor) when such compounds are administered to a mammal (e.g., by allowing an orally administered compound to be more readily absorbed into the blood) or which enhance delivery of a compound described herein (e.g., a FAK inhibitor, a MEK inhibitor) to a biological compartment, e.g., relative to general distribution of a compound described herein (e.g., a FAK inhibitor, a MEK inhibitor). Preferred prodrugs include derivatives where a group which enhances aqueous solubility or active transport through the gut membrane is appended to the structure of the formulae of the compounds described herein (e.g., a FAK inhibitor, a MEK inhibitor).

The term, “oral dosage form,” as used herein, refers to a composition or medium used to administer an agent, e.g., VS-6063, to a subject. Typically, an oral dosage form is administered via the mouth, however, “oral dosage form” is intended to cover any substance which is administered to a subject and is absorbed across a membrane, e.g., a mucosal membrane, of the gastrointestinal tract, including, e.g., the mouth, esophagus, stomach, small intestine, large intestine, and colon. For example, “oral dosage form” covers a solution which is administered through a feeding tube into the stomach.

The term, “treat” or “treatment,” as used herein, refers to the application or administration of a compound, alone or in combination with, an additional agent to a subject, e.g., a subject who has a disorder (e.g., a disorder as described herein), a symptom of a disorder, or a predisposition toward a disorder, with the purpose to cure, heal, alleviate, relieve, alter, remedy, ameliorate, improve or affect the disorder.

As used herein, the phrase “synergistic effect” refers to a greater than additive effect (e.g., therapeutic effect) of two or more compounds or compositions. An exemplary synergistic effect includes administration of an amount of a FAK inhibitor (e.g., VS-6063, or a pharmaceutically acceptable salt thereof) used (e.g., administered) in combination with an amount of a MEK inhibitor (e.g., pimasertib, or a pharmaceutically acceptable salt thereof) that results in a therapeutic effect that is greater than the additive therapeutic effect of each inhibitor used alone.

As used herein, the term “subject” is intended to include human and non-human animals. Exemplary human subjects include a human subject having a disorder, e.g., a disorder described herein. The term “non-human animals” of the invention includes all vertebrates, e.g., non-mammals (such as chickens, amphibians, reptiles) and mammals, such as non-human primates, domesticated and/or agriculturally useful animals. e.g., sheep, dog, cat, cow, pig, etc.

Combinations

The present invention relates to, inter alia, combinations of a FAK inhibitor and a MEK inhibitor (i.e., a FAK inhibitor in combination with a MEK inhibitor), and methods for treating abnormal cell growth, e.g., cancer, comprising administering to a subject in need thereof, a FAK inhibitor in combination with a MEK inhibitor.

The phrase, “in combination with,” and the terms “co-administration,” “co-administering,” or “co-providing”, as used herein in the context of the administration of a compound described herein or a therapy described herein, means that two (or more) different compounds or therapies are delivered to the subject during the course of the subject's affliction with the disease or disorder (e.g., a disease or disorder as described herein, e.g., cancer), e.g., two (or more) different compounds or therapies are delivered to the subject after the subject has been diagnosed with the disease or disorder (e.g., a disease or disorder as described herein, e.g., cancer) and before the disease or disorder has been cured or eliminated or treatment has ceased for other reasons. In some embodiments, the delivery of one compound or therapy is still occurring when the delivery of the second begins, so that there is overlap in terms of administration. This is sometimes referred to herein as “simultaneous” or “concurrent delivery.” In other embodiments, the delivery of one compound or therapy ends before the delivery of the other compound or therapy begins. In some embodiments of either case, the treatment (e.g., administration of compound, composition, or therapy) is more effective because of combined administration. For example, the second compound or therapy is more effective, e.g., an equivalent effect is seen with less of the second compound or therapy, or the second compound or therapy reduces symptoms to a greater extent, than would be seen if the second compound or therapy were administered in the absence of the first compound or therapy, or the analogous situation is seen with the first compound or therapy. In some embodiments, delivery is such that the reduction in a symptom, or other parameter related to the disorder is greater than what would be observed with one compound or therapy delivered in the absence of the other. The effect of the two compounds or therapies can be partially additive, wholly additive, or great than additive (e.g., synergistic). The delivery can be such that the first compound or therapy delivered is still detectable when the second is delivered.

In some embodiments, the first compound or therapy and second compound or therapy can be administered simultaneously (e.g., at the same time), in the same or in separate compositions, or sequentially. Sequential administration refers to administration of one compound or therapy before (e.g., immediately before, less than 5, 10, 15, 30, 45, 60 minutes; 1, 2, 3, 4, 6, 8, 10, 12, 16, 20, 24, 48, 72, 96 or more hours; 4, 5, 6, 7, 8, 9 or more days; 1, 2, 3, 4, 5, 6, 7, 8 or more weeks before) administration of an additional, e.g., secondary, compound or therapy. The order of administration of the first and secondary compound or therapy can also be reversed.

The combinations described herein, e.g., a FAK inhibitor in combination with a MEK inhibitor, can be a first line treatment for abnormal cell growth. e.g., cancer, i.e., it is used in a patient who has not been previously administered another drug intended to treat the cancer; a second line treatment for the cancer, i.e., it is used in a subject in need thereof who has been previously administered another drug intended to treat the cancer; a third or fourth treatment for the cancer, i.e., it is used in a subject who has been previously administered two or three other drugs intended to treat the cancer.

In some embodiments, the combinations described herein, e.g., a FAK inhibitor in combination with a MEK inhibitor, is a first line treatment for the cancer. In some embodiments, the combinations described herein, e.g., a FAK inhibitor in combination with a MEK inhibitor, is a second line treatment for the cancer.

FAK Inhibitors

Compound VS-6063

An example of a FAK inhibitor is the compound VS-6063 (e.g., VS-6063 free base):

or a pharmaceutically acceptable salt thereof (e.g., VS-6063 hydrochloride), as disclosed in U.S. Pat. No. 7,928,109. VS-6063 is also known as defactinib or PF-04554878.

VS-6063 is a potent inhibitor of the FAK protein tyrosine kinases, and may be adapted to therapeutic use as antiproliferative agents (e.g., anticancer), antitumor (e.g., effective against solid tumors), antiangiogenesis (e.g., stop or prevent proliferation of blood vessels) in mammals, particularly in humans. VS-6063 may be useful in the prevention and treatment of non-hematolotic malignancies. Moreover, VS-6063 may be useful in the prevention and treatment of a variety of human hyperproliferative disorders, including malignant and benign tumors of the liver, kidney, bladder, breast, gastric, ovarian, colorectal, prostate, pancreatic, lung, vulval, thyroid, hepatic carcinomas, sarcomas, glioblastomas, head and neck, and other hyperplastic conditions such as benign hyperplasia of the skin (e.g., psoriasis) and benign hyperplasia of the prostate (e.g., BPH). VS-6063 may also be useful in the prevention and treatment of disorders such as mesothelioma.

MEK Inhibitors

A MEK inhibitor can be a small molecule or biologic inhibitor of the mitogen-activated protein kinase (MAPK) enzymes MEK1 and/or MEK2 (e.g., MAPK/ERK pathway).

Examples of MEK inhibitors include:

-   -   Trametinib (also known as Mekinst, GSK1120212)

-   -   Pimasertib (also known as AS703026, MSC1936369B):

MEK inhibitor GDC-0623 specifically         inhibits mitogen-activated protein kinase kinase (MEK or MAP/ERK         kinase), resulting in inhibition of growth factor-mediated cell         signaling and tumor cell proliferation. MEK is a key component         of the RAS/RAF/MEK/ERK signaling pathway that regulates cell         growth; constitutive activation of this pathway has been         implicated in many cancers. Hatzivassiliou et al, Nature 2013,         501 (7466), 232-6.

Disease and Disorders

Abnormal Cell Growth

Abnormal cell growth, as used herein and unless otherwise indicated, refers to cell growth that is independent of normal regulatory mechanisms (e.g., loss of contact inhibition). This includes the abnormal growth of: (1) tumor cells (tumors) that proliferate, for example, by expressing a mutated tyrosine kinase or overexpression of a receptor tyrosine kinase; (2) benign and malignant cells of other proliferative diseases, for example, in which aberrant tyrosine kinase activation occurs; (3) any tumors that proliferate, for example, by receptor tyrosine kinases; (4) any tumors that proliferate, for example, by aberrant serine/threonine kinase activation; and (5) benign and malignant cells of other proliferative diseases, for example, in which aberrant serine/threonine kinase activation occurs. Abnormal cell growth can refer to cell growth in epithelial (e.g., carcinomas, adenocarcinomas); mesenchymal (e.g., sarcomas (e.g. leiomyosarcoma. Ewing's sarcoma)); hematopoetic (e.g., lymphomas, leukemias, myelodysplasias (e.g., pre-malignant)); or other (e.g., melanoma, mesothelioma, and other tumors of unknown origin) cells.

Neoplastic Disorders

Abnormal cell growth can refer to a neoplastic disorder. A “neoplastic disorder” is a disease or disorder characterized by cells that have the capacity for autonomous growth or replication. e.g., an abnormal state or condition characterized by proliferative cell growth. An abnormal mass of tissue as a result of abnormal cell growth or division, or a “neoplasm.” can be benign, pre-malignant (carcinoma in situ) or malignant (cancer).

Exemplary neoplastic disorders include: carcinoma, sarcoma, metastatic disorders (e.g., tumors arising from prostate, colon, lung, breast and liver origin), hematopoietic neoplastic disorders. e.g., leukemias, metastatic tumors. Treatment with the compound may be in an amount effective to ameliorate at least one symptom of the neoplastic disorder, e.g., reduced cell proliferation, reduced tumor mass, etc.

Cancer

The inventive methods of the present invention may be useful in the prevention and treatment of cancer, including for example, solid tumors, soft tissue tumors, and metastases thereof. The disclosed methods are also useful in treating non-solid cancers. Exemplary solid tumors include malignancies (e.g., sarcomas, adenocarcinomas, and carcinomas) of the various organ systems, such as those of lung, breast, lymphoid, gastrointestinal (e.g., colon), and genitourinary (e.g., renal, urothelial, or testicular tumors) tracts, pharynx, prostate, and ovary. Exemplary adenocarcinomas include colorectal cancers, renal-cell carcinoma, liver cancer (e.g., Hepatocellular carcinoma), non-small cell carcinoma of the lung, pancreatic (e.g., metastatic pancreatic adenocarcinoma) and cancer of the small intestine.

The cancer can include mesothelioma; neurofibromatosis; e.g., neurofibromatosis type 2, neurofibromatosis type 1; renal cancer, lung cancer, non small cell lung cancer; liver cancer, thyroid cancer, ovarian; breast cancer; a nervous system tumor; schwannoma; meningioma; schwannomatosis; neuroma acoustic; adenoid cystic carcinoma; ependymoma; ependylmal tumors, or any other tumor which exhibits decreased merlin expression and/or mutation, and/or deletion and/or promotor hypermethylation of the NF-2 gene. In some embodiments, the cancer is renal cancer.

The cancer can include cancers characterized as comprising cancer stem cells, cancer associated mesenchymal cells, or tumor initiating cancer cells. The cancer can include cancers that have been characterized as being enriched with cancer stem cells, cancer associated mesenchymal cells, or tumor initiating cancer cells (e.g., a tumor enriched with cells that have undergone an epithelial-to-mesenchymal transition or a metastatic tumor).

The cancer can be a primary tumor, i.e., located at the anatomical site of tumor growth initiation. The cancer can also be metastatic, i.e., appearing at least a second anatomical site other than the anatomical site of tumor growth initiation. The cancer can be a recurrent cancer, i.e., cancer that returns following treatment, and after a period of time in which the cancer was undetectable. The recurrent cancer can be anatomically located locally to the original tumor, e.g., anatomically near the original tumor; regionally to the original tumor, e.g., in a lymph node located near the original tumor; or distantly to the original tumor, e.g., anatomically in a region remote from the original tumor.

The cancer can also include for example, but is not limited to, epithelial cancers, breast lung, pancreatic, colorectal (e.g., metastatic colorectal, e.g., metastatic K Ras mutated), prostate, head and neck, melanoma (e.g., N Ras mutated locally advanced or metastatic malignant cutaneous melanoma), acute myelogenous leukemia, and glioblastoma.

Cancer Combination Therapies

In some embodiments, the methods and compositions described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) is administered together with an additional therapy (e.g., cancer treatment). In one embodiment, a mixture of one or more compounds or pharmaceutical compositions may be administered with the combination described herein, e.g., a FAK inhibitor in combination with a MEK inhibitor, to a subject in need thereof. In yet another embodiment, one or more compounds or compositions (e.g., pharmaceutical compositions) may be administered with the combination described herein, e.g., a FAK inhibitor in combination with a MEK inhibitor, for the treatment or avoidance of various diseases, including, for example, cancer, diabetes, neurodegenerative diseases, cardiovascular disease, blood clotting, inflammation, flushing, obesity, aging, stress, etc. In various embodiments, combination therapies comprising a compound or pharmaceutical composition described herein may refer to (1) pharmaceutical compositions that comprise one or more compounds in combination with the combination described herein, e.g., a FAK inhibitor in combination with a MEK inhibitor; and (2) co-administration of one or more compounds or pharmaceutical compositions described herein with the combination described herein, e.g., a FAK inhibitor in combination with a MEK inhibitor, wherein the compound or pharmaceutical composition described herein have not been formulated in the same compositions. In some embodiments, the combinations described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) is administered with an additional treatment (e.g., an additional cancer treatment). In some embodiments, the additional treatment (e.g., an additional cancer treatment) can be administered simultaneously (e.g., at the same time), in the same or in separate compositions, or sequentially. Sequential administration refers to administration of one treatment before (e.g., immediately before, less than 5, 10, 15, 30, 45, 60 minutes; 1, 2, 3, 4, 6, 8, 10, 12, 16, 20, 24, 48, 72, 96 or more hours; 4, 5, 6, 7, 8, 9 or more days; 1, 2, 3, 4, 5, 6, 7, 8 or more weeks before) administration of an additional, e.g., secondary, treatment (e.g., a compound or therapy). The order of administration of the first and secondary compound or therapy can also be reversed.

Exemplary cancer treatments include, for example: chemotherapy, targeted therapies such as antibody therapies, immunotherapy, and hormonal therapy. Examples of each of these treatments are provided below.

Chemotherapy

In some embodiments, a combination described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) is administered with a chemotherapy. Chemotherapy is the treatment of cancer with drugs that can destroy cancer cells. “Chemotherapy” usually refers to cytotoxic drugs which affect rapidly dividing cells in general, in contrast with targeted therapy. Chemotherapy drugs interfere with cell division in various possible ways, e.g., with the duplication of DNA or the separation of newly formed chromosomes. Most forms of chemotherapy target all rapidly dividing cells and are not specific for cancer cells, although some degree of specificity may come from the inability of many cancer cells to repair DNA damage, while normal cells generally can.

Examples of chemotherapeutic agents used in cancer therapy include, for example, antimetabolites (e.g., folic acid, purine, and pyrimidine derivatives) and alkylating agents (e.g., nitrogen mustards, nitrosoureas, platinum, alkyl sulfonates, hydrazines, triazenes, aziridines, spindle poison, cytotoxic agents, toposimerase inhibitors and others). Exemplary agents include Aclarubicin, Actinomycin, Alitretinon, Altretamine, Aminopterin, Aminolevulinic acid, Amrubicin, Amsacrine, Anagrelide, Arsenic trioxide, Asparaginase, Atrasentan, Belotecan, Bexarotene, endamustine, Bleomycin, Bortezomib, Busulfan, Camptothecin, Capecitabine, Carboplatin, Carboquone, Carmofur, Carmustine, Celecoxib, Chlorambucil, Chlormethine, Cisplatin, Cladribine, Clofarabine, Crisantaspase, Cyclophosphamide, Cytarabine, Dacarbazine, Dactinomycin, Daunorubicin, Decitabine, Demecolcine, Docetaxel, Doxorubicin, Efaproxiral, Elesclomol, Elsamitrucin, Enocitabine, Epirubicin, Estramustine, Etoglucid, Etoposide, Floxuridine, Fludarabine, Fluorouracil (5FU), Fotemustine, Gemcitabine, Gliadel implants, Hydroxycarbamide, Hydroxyurea, Idarubicin, Ifosfamide, Irinotecan, Irofulven, Ixabepilone, Larotaxel, Leucovorin, Liposomal doxorubicin, Liposomal daunorubicin, Lonidamine, Lomustine, Lucanthone, Mannosulfan, Masoprocol, Melphalan, Mercaptopurine, Mesna, Methotrexate, Methyl aminolevulinate, Mitobronitol, Mitoguazone, Mitotane, Mitomycin, Mitoxantrone, Nedaplatin, Nimustine, Oblimersen, Omacetaxine, Ortataxel, Oxaliplatin, Paclitaxel, Pegaspargase, Pemetrexed, Pentostatin, Pirarubicin, Pixantrone, Plicamycin, Porfimer sodium, Prednimustine, Procarbazine, Raltitrexed, Ranimustine, Rubitecan, Sapacitabine, Semustine, Sitimagene ceradenovec, Strataplatin, Streptozocin, Talaporfin, Tegafur-uracil, Temoporfin, Temozolomidc, Teniposide, Tesetaxel, Testolactone, Tetranitrate, Thiotepa, Tiazofurine, Tioguanine, Tipifarnib, Topotecan, Trabectedin, Triaziquone, Triethylenemelamine, Triplatin, Tretinoin, Treosulfan, Trofosfamide, Uramustine, Valrubicin, Verteporfin, Vinblastine, Vincristine, Vindesine, Vinflunine, Vinorelbine, Vorinostat, Zorubicin, and other cytostatic or cytotoxic agents described herein.

Because some drugs work better together than alone, two or more drugs are often given at the same time or sequentially. Often, two or more chemotherapy agents are used as combination chemotherapy. In some embodiments, the chemotherapy agents (including combination chemotherapy) can be used in combination with a combination described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor).

Targeted Therapy

In some embodiments, a combination described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) is administered with a targeted therapy. Targeted therapy constitutes the use of agents specific for the deregulated proteins of cancer cells. Small molecule targeted therapy drugs are generally inhibitors of enzymatic domains on mutated, overexpressed, or otherwise critical proteins within the cancer cell. Prominent examples are the tyrosine kinase inhibitors such as Axitinib, Bosutinib, Cediranib, desatinib, erolotinib, imatinib, gefitinib, lapatinib, Lestaurtinib, Nilotinib, Semaxanib, Sorafenib, Sunitinib, and Vandetanib, and also cyclin-dependent kinase inhibitors such as Alvocidib and Seliciclib, Monoclonal antibody therapy is another strategy in which the therapeutic agent is an antibody which specifically binds to a protein on the surface of the cancer cells. Examples include the anti-HER2/neu antibody trastuzumab (HERCEPTIN®) typically used in breast cancer, and the anti-CD20 antibody rituximab and Tositumomab typically used in a variety of B-cell malignancies. Other exemplary anbitodies include Ctuximab, Panitumumab, Trastuzumab, Alemtuzumab, Bevacizumab, Edrecolomab, and Gemtuzumab. Exemplary fusion proteins include Aflibercept and Denileukin diftitox. In some embodiments, the targeted therapy can be used in combination with a combination described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor).

Targeted therapy can also involve small peptides as “homing devices” which can bind to cell surface receptors or affected extracellular matrix surrounding the tumor. Radionuclides which are attached to these peptides (e.g., RGDs) eventually kill the cancer cell if the nuclide decays in the vicinity of the cell. An example of such therapy includes BEXXAR®.

Immunotherapy

In some embodiments, a combination described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) is administered with an immunotherapy. Cancer immunotherapy refers to a diverse set of therapeutic strategies designed to induce the patient's own immune system to fight the tumor. Contemporary methods for generating an immune response against tumors include intravesicular BCG immunotherapy for superficial bladder cancer, and use of interferons and other cytokines to induce an immune response in subjects with renal cell carcinoma and melanoma.

Allogeneic hematopoietic stem cell transplantation can be considered a form of immunotherapy, since the donor's immune cells will often attack the tumor in a graft-versus-tumor effect. In some embodiments, the immunotherapy agents can be used in combination with a combination as described herein, e.g., a FAK inhibitor in combination with a MEK inhibitor.

Hormonal Therapy

In some embodiments, a combination described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) is administered with a hormonal therapy. The growth of some cancers can be inhibited by providing or blocking certain hormones. Common examples of hormone-sensitive tumors include certain types of breast and prostate cancers. Removing or blocking estrogen or testosterone is often an important additional treatment. In certain cancers, administration of hormone agonists, such as progestogens may be therapeutically beneficial. In some embodiments, the hormonal therapy agents can be used in combination with a combination described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor).

Radiation Therapy

The combinations described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) can be used in combination with directed energy or particle, or radioisotope treatments, e.g., radiation therapies, e.g., radiation oncology, for the treatment of proliferative disease, e.g., cancer, e.g., cancer associated with cancer stem cells. The combinations described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) may be administered to a subject simultaneously or sequentially along with the directed energy or particle, or radioisotope treatments. For example, the combinations described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) may be administered before, during, or after the directed energy or particle, or radioisotope treatment, or a combination thereof. The directed energy or particle therapy may comprise total body irradiation, local body irradiation, or point irradiation. The directed energy or particle may originate from an accelerator, synchrotron, nuclear reaction, vacuum tube, laser, or from a radioisotope. The therapy may comprise external beam radiation therapy, teletherapy, brachytherapy, sealed source radiation therapy, systemic radioisotope therapy, or unsealed source radiotherapy. The therapy may comprise ingestion of, or placement in proximity to, a radioisotope, e.g., radioactive iodine, cobalt, cesium, potassium, bromine, fluorine, carbon. External beam radiation may comprise exposure to directed alpha particles, electrons (e.g., beta particles), protons, neutrons, positrons, or photons (e.g., radiowave, millimeter wave, microwave, infrared, visible, ultraviolet. X-ray, or gamma-ray photons). The radiation may be directed at any portion of the subject in need of treatment.

Surgery

The combinations described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) can be used in combination with surgery, e.g., surgical exploration, intervention, biopsy, for the treatment of proliferative disease, e.g., cancer, e.g., cancer associated with cancer stem cells. The combinations described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) may be administered to a subject simultaneously or sequentially along with the surgery. For example, the combinations described herein (e.g., a FAK inhibitor in combination with a MEK inhibitor) may be administered before (pre-operative), during, or after (post-operative) the surgery, or a combination thereof. The surgery may be a biopsy during which one or more cells are collected for further analysis. The biopsy may be accomplished, for example, with a scalpel, a needle, a catheter, an endoscope, a spatula, or scissors. The biopsy may be an excisional biopsy, an incisional biopsy, a core biopsy, or a needle biopsy, e.g., a needle aspiration biopsy. The surgery may involve the removal of localized tissues suspected to be or identified as being cancerous. For example, the procedure may involve the removal of a cancerous lesion, lump, polyp, or mole. The procedure may involve the removal of larger amounts of tissue, such as breast, bone, skin, fat, or muscle. The procedure may involve removal of part of, or the entirety of, an organ or node, for example, lung, throat, tongue, bladder, cervix, ovary, testicle, lymph node, liver, pancreas, brain, eye, kidney, gallbladder, stomach, colon, rectum, or intestine. In one embodiment, the cancer is breast cancer, e.g., triple negative breast cancer, and the surgery is a mastectomy or lumpectomy.

EXAMPLES

The disclosure is further described in the following examples, which do not limit the scope of the claims.

Materials and Methods

Cell Lines:

Cancer cell lines were purchased from American Type Culture Collection (Manassas, Va.) and cultured under ATCC recommended standard culture conditions. Mero-41 (mesothelioma cell line) were purchased from Sigma-Aldrich (St. Louis, Mo.) and cultured under ECACC recommended standard culture conditions. MDA-MB-231 (triple negative breast cancer cell line) were cultured under ECACC recommended standard culture conditions. TOV-21G (ovarian clear cell carcinoma cell line) were cultured under ECACC recommended standard culture conditions. Growth media for all cell lines were supplcmcntcd with penicillin (100 units/ml)/streptomycin (100 μg/ml). Medium included a 1:1 mixture of MCDB 105 medium ((+1.5 g/L sodium bicarbonate): Medium 199 (+2.2 g/L sodium bicarbonate); 15% FBS.

A. Combination Screen Format:

A full 9×9 matrix format was used to evaluate the combination effect between VS-6063 and MEK inhibitors across a wide concentration range and dose ratios. Compound were used at the top concentration 10 uM in a 2-fold dilution. Paclitaxel was dosed at the top concentration 1 uM in a 3-fold dilution.

B. Assays

A ‘Matrigel on-top’ (MoT) assay where cells were propagated in a 3-dimensional culture was used. Cells were plated above a dense base layer of Matrigcl (BD Biosciences, Franklin Lakes, N.J.), diluted 1:1 with culture medium. Single cell preparations were resuspended in dilute Marigel (1:50 in culture medium) and seeded to cover the Matrigel base layer. This ensured that ovarian cancer cells were surrounded with extracellular matrix (ECM) components, of which collagen and laminin are the major Matrigel constituents. Cells were seeded in a density of 500 cells per well in 384-well black Ultra-low attachment plates with clear bottom (Corning, Tewksbury Mass.). Twenty-four hours after incubation, cells were treated with VS-6063 at various concentrations, or a combination of VS-6063 and MEK inhibitor at various concentrations. Cell survival/proliferation was assessed by CellTiter-Glo® Luminescent Cell Viability Assay (Promega, Madison, Wis.). A T₀ reading (when compound was added) and a T₉₆ reading (96 hours incubation with the compounds) were obtained using Envision 2104 Multilabel Reader (PerkinElmer, Boston, Mass.).

C. Combination Analytical Methods

Combination effects were evaluated by comparing the averaged viability/inhibition to three different null reference models derived from the single agent activities.

Bliss Independence Model

Bliss independence model predicts interaction effects with the assumption that single agents act in a mutually non-exclusive manner and each agent contributes independently to the resulting effect (Bliss et al. 1939). The expected additivity effect is the statistical expectation for the combined effect from independent inhibitors: Mathematically, Bliss (F_(U))=Fv_(UA1)×F_(UA2), where F_(UA1) and F_(UA2) are the unaffected fraction when treated with compounds A1 and A2, respectively.

Highest Single Agent (HSA) Model/Gaddum's Non-Interaction Model

Gaddum's non-interaction model states that the single agents must necessarily be helping each other if the effect of a combination exceeds either of the single agents (Berenbaum et al, 1989). Mathmatically, HSA (F_(a))=max (Fa_(A1), Fa_(A2)), where Fa_(A1) and Fa_(A2) are the affected fraction when treated with compounds A1 and A2, respectively.

Loewe Additivity Model

Loewe additivity model assumes that two inhibitors act on a target through a similar mechanism and that the inhibitors differ only in potencies (Fitzgerald et al, 2006). Combination effect over Loewe additivity model can be considered as a decrease in the total effective drug dose in combination compared to that of the single agents required to achieve a given effect level. Synergy can be measured in term of combination index. CI=D_(A1)/d_(A1)+D_(A2)/d_(A2) where D_(A1) and D_(A2) are the combination doses of compounds A1 and A2; d_(A1) and d_(A2) are the single agent doses of compounds A1 and A2 at the same affected fraction achieved by the combination doses, CI<1 for synergistic combinations and CI>1 for antagonistic combinations. Loewe (F_(a)) is the affected fraction that satisfies (D_(A1)/d_(A1(Loewe)))+(D_(A2)/d_(A2(Loewe)))=1 where d_(A1(Loewe)) and d_(A2(Loewe)) are the effective concentration at Loewe(F_(a)) of the single agent compounds A1 and A2.

Results

FIGS. 1 to 12 show exemplary plots and analyses of cell viability of mesothelioma and breast cancer cells in the presence of exemplary FAK inhibitor VS-6063 with and without exemplary MEK inhibitors GDC-0623, cobimetinib, AZD-6244, pimasertib, and trametinib. Comparative plots of viability in the presence and absence of MEK inhibitors suggest a more than additive effect (e.g., a synergistic effect) of the combination of a FAK inhibitor, e.g., VS-6063, and a MEK inhibitor (e.g., GDC-0623, cobimetinib, AZD-6244, pimasertib, and trametinib). Plots modeling the combination effects (e.g., Bliss Independence Model, Highest Single Agent (HSA) Model, and Loewe Additivity Model) are included which show how the activity (e.g., effect on cell viability) of the given combination of FAK and MEK inhibitors would appear on the plot based on an additive effect of inhibition of the two inhibitors.
